He'll remain the best tennis player in the world by a distance and win one or two Slams. He will systematically make semis and finals of big events (Slams, Masters, WTF). Pretty much the same as in 2012, really, a clear #1 although not as overwhelmingly dominant as in 2011. Also it'd be cool if he completed his career Slam at RG, which is definitely a possibility, especially with Nadal out for so long.

I think his Slam SF streak might be snapped as he might lose a QF, most likely venue for that being Wimbledon of course, but wouldn't be surprised if he kept it going either.

1. Win French Open to complete his career Grand Slam
2. Get his revenge in a slam on Mugray
3. Remain and finish 2013 ranked #1 for the 3rd consecutive year
4. Maintain his grand slam SF streak (currently sitting at 10)
5. More Federer vs Djokovic matches (my 2 favourites and I love watching this match-up)
